Abstract
A biliary stricture is an abnormal narrowing in the ductal drainage system of the liver. There are many etiologies of biliary stricture, the most common and ominous of which is malignancy, either primary or metastatic.It is difficult to obtain pathological tissue of the terminal end of the common bile duct. A 72-year-old woman, complained of abdominal pain for 2 months, underwent cholecystectomy for acute cholecystitis 11 years ago. Abdominal CT and MRI examination revealed soft tissue occupation (12*8 mm) in the duodenal papillary area, and endoscopic ultrasonography revealed a hypoechoic lesion (11.1*10.7 mm) in the ampulla. We performed ERCP, and intraoperative biliary cell brushing on the patient, but no positive pathological results were obtained. We further performed novel 9F digital single operator cholangioscopy system (DSOC) (eyeMAX, Micro-Tech, Nanjing, China) and observed intraoperative hyperemia and edema of the mucosa in the terminal end of the common bile duct, presenting fish-like changes with mucous attachment and clear lesion boundaries. The pathological results suggested cholangiocarcinoma.
